SURGICAL BAKER.

Application filed August 3; 1925. Serial No. 47,786.

My invention has for its object an electrical surgical baker for use in the treement of certain diseases and conditions as for instance, arthritis. Electrical surgical bakers have heretofore been constructed for contained therein.

this purpose but they have been heavy and cumbersome and not adapted to the hand treatment of special parts of the body. The particular object of the present invention is to provide an electric baker which can be held by'the nurse or physician in one hand or attached to an adjustable stand and directed toward whatever portion of the body the patient is to be treated. To this end it is'essential that the baker be very light but he of durable construction and capable of producing a proper distribution of the rays from the filaments of the lamps The baker embodying my present invention is very light and convenient to handle and it produces the best possible diffusion of light and heat for the purposes intended without producing socalled burning or focussing points. Three or more degrees of light and heat may be produced according to the number and size of the lamps employed in the baker.

The invention will be fully understood from the following description when taken in connection with the accompanying drawings and the novel features thereof will be pointed out and clearly defined in the claims at the close of this specification.

Referring to the drawings:

Fig. 1 is a top plan view partly in section of a baker embodying my invention.

Fig. 2 is a section on line 22, Fig. 1 showing the interior construction.

Fig. 3 is a front elevation of the baker shown in Fig. 1.

Fig. 4 is asection on line 44, Fig. 3.

Referring now to the drawings:

The body of the baker is composed of a shell 11 which between the points a and b is bent to a cylindrical shape about a relatively large diameter while from a to c and from b to (Z it is bent about a small diameter and at 0 and (Z and has its edges rolled into tubes t which forms a finish for the edges of the sheet. At 13 and 14 are shown top and bottom members which are essentially flat plates of kidney shape, the edges of which are crimped over the top and bottom edges of the body member 11 as shown at e and f respectively. The construction of the joint is the ordinary crimp ing construction and is shown in Fig. 4. The tubular portions 25 abut the top and bottoms members and act as posts to stiffen the whole structure.

At 15 is shown a lamp shelf and at 16 a front wall. The frontedge of the lamp shelf 15 and the upper edge of the front wall 16 are crimped together at g as shown in Fig. 4, so thatthey form one piece. The back edge of the lamp shelf is turned down as shown at 17 so that it lies parallel with the inner surface of the body member 11. The lower edge of the front wall 16 fits inside the crimped edge of the bottom 14: and the parts are held in place by two bolts 19 and 20 which extend from the bottom member and are held in place by nuts 21. In suitable holes in the lamp shelf 15 are placed insulating bases 22, 23 and 24, preferably, but not necessarily for three incandescent lamps 25, 26 and 27 which are of candle shape with filaments which extend lengthwise of the lamp and parallel with the inner surface of the body member.

At 28 is shown a fixed hail of U-shape, the legs of which are extended over and lie parallel with the top and bottom faces of the top and bottom members being secured thereto in any suitable manner as by rivets 29. The bail does not contact. with the. body of the baker and therefore heats up less than it otherwise would. The bail is supplied with two lugs 30 and 31 to which is secured a handle 32 by a bolt 33 furnished with a thumb nut 34 by which the angle of the handle can be adjusted as desired. The electric wire which supplies current is shown at 35 and passes through the handle to a suitable switch 36 shown in dotted lines in Fig. 2 and operated by a thumb member 37. The wires passout through the end of the handle as shown at 7 and thence through an insulating thimble bushing 8 into the interior of the casing below the lamp shelf 15 as shown in Fig. 2. The wires 7 form a flexible connection between the hand and body and therefore do not interfere with the adjustment of the handle to any convenient position. It will be understood of course that a suitable switch or switches and any convenient wiring for the lamps may be provided as desired. By loosening one or more of the lamps in their respective sockets the amount of heat can be diminished.

ill

excellent and at the same In practice, I make the body member 11 of aluminum which is capable of receiving a high polish and therefore the body member serves not only as the frame of the structure of the device but also its inside surface acts as the reflector. The inside of the top member 13 and the top surface of the lamp shelf 15 may both be polished and serve to increase the reflective powers of the device. I find that when three lamps are employed and the body is made as a portion of a cylinder, the distribution of light and heat is time the device has a conven ent shape so that it can be readily applied to portions of the patients body. The extremely light weight resulting from the construction described makes it possible to use the device for considerable periods of time without fatigue.

What I claim is: l

.1. An electrical. surgical baker comprising a curved shell forming part of a cylinder, top and bottom members secured to the shell at right angles thereto, a shelf between the top and bottom members, a bail on the outside of the shell, a handle secured thereto, incandescent lamps secured to the shelf, and electrical connections passing through the handle and the shell into the space below the shelf.

2. The electrical surgical baker comprishighly polished metal mg a curved sheet of the inner surface of which acts a reflector,

top and bottom members secured thereto by crimping, the opposite edges of the shell being rolled into tubular form to form stiffeners which extend from the bottom member to the top member, a lamp shelf intermedi ate the top and bottom members and incandescent lamps secured to the said shelf and arranged parallel to the axis of the cylindrical portion of the shell.

.3. The electrical surgical baker comprising a curved shell forming part of a cylinder top and bottom members secured to the shell at right angles thereto, the opposite shell into the chamber edges of the shell being rolled into tubular form to form stiffening posts extending from the top member to the bottom member, a shelf intermediate said top and bottom members, a front enclosure extending from the shelf to the bottom member and With the shelf forming a chamber at the bottom of the device, incandescent lamps supported on the shelf parallel to the axis of the cylindrical portion of the shell, a handle secured to the outside of the shell, and electrical connections extending through the handle and the beneath the shell.

i. The electrical surgical baker comprising a curved shell forming part of a cylinder, top and bottom members secured to the shell at right angles thereto, opposite edges of the shell being rolled into tubular form to form stiffening posts extending from the top member to the bottom member, a shelf intermediate the top and bottom members, a front "member forming an enclosure beneath the shelf, electric lamps supported on the shelf, a bail secured to the top and bottom members and extending parallel with the rear of the shell but at a distance from it, a pivoted handle connected to said bail, a switch in said handle, and electrical connections extending through the handle an the shell into the chamber beneath the shell.

5. The electrical surgical baker comprising a curved shell forming part of a cylinder, top and bottom members secured to the shell at right angles thereto, a shelf intermediate said top and bottom members, a front enclosure extending from the shelf to the bottom member and with the shelf forming a chamber at the bottom of the device, incandescent lamps supported on the shelf, a. handle secured to the outside of the shell, electrical connections extending through the handle and the shell into the chamber beneath the shell, and an electrical switch in the handle.

In testimony whereof I aflix my signature.
